  • In this paper we present a microprocessor-based interpolator using algebraic arithmetic method. The interpolator consists of 2910 "bit-slice" microprocessor chips and 0.5K ROMs of microprogram memory. The system design is an instruction-data-based architecture with 250ns cycle time. A significant feature of the interpolator is that it has flexibility, very fast interpolatioon speed of (max) 250K pulses/sec, and performs additional functions simultaneously. Throughout the paper detailed explanations are given as to how one can design the hardware and software of the interpolator efficently.

  • In this paper, a pre-layout design approach for high-speed microprocessor is proposed. For multilayer PCB stark up configuration as well as selection and placement of decoupling capacitors, an effective solution for reducing SSN and EMI is obtained by modeling and simulation of complete power distribution system. The system model includes VRM, decoupling capacitors, multiple power and ground planes for core voltage, vias, as well as microprocessor. Finally, the simulation results are verified by measurements data.

  • Programmable logic controller (PLC) is widely used in manufacturing system or process control. This paper presents the design of a 32-bit microprocessor for a sequence control using an Application Specification Integrated Circuit (ASIC). The 32-bit microprocessor was designed by a VHDL with top down method; the program memory was separated from the data memory for high speed execution of 274 specified sequence instructions. Therefore it was possible that sequence instructions could be operated at the same time during the instruction fetch cycle. And in order to reduce the instruction decoding time and the interface time of the data memory interface, an instruction code size was implemented by 32-bits. And the real time debugging as single step run, break point run was implemented. Pulse instruction, step controller, master controllers, BIN and BCD type arithmetic instructions, barrel shit instructions were implemented for many used in PLC system. The designed microprocessor was synthesized by the S1L50000 series which contains 70,000 gates with 0.65um technology of SEIKO EPSON. Finally, the benchmark was performed to show that designed 32-bit microprocessor has better performance than Q4A PLC of Mitsubishi Corporation.

  • In this paper, to design 8 bit RISC Microprocessor, a method of Clock Gating to reduce electric power consumption is proposed. In order to examine the priority, the comparison results of between a 8 bit Microprocessor which is not considered Low Power consumption and which is considered Low Power consumption using a methods of Clock Gating are represented. Within the a few periods, the results of comparing with a Microprocessor not considered the utilization of Clock Gating shows that the reduction of dynamic dissipation is minimized up to 21.56%.

  • In this paper we designed CAMC-SP, the microprocessor embedded 2-axis motor control chip which controls a precise pulse motor by generating the pulse needed to control step motor, DC servo and AC servo motor. This design enables to decrease costs and to minimize a size. First we designed risc type 8-bit microprocessor compatible with PIC16C84, second we designed pulse motor controller. CAMC-SP is integrated of those two block. We designed CAMC-SP by VHDL and we testified to the Performance of it by performing functional simulation.
